stream.ReadTimeout' threw an exception of type 'System.InvalidOperationException
Jun 18, 2019 06:08 PM|demoninside9|LINK
Hi All,
I am using below code to upload file.
if (FileUpload1.HasFile) { Stream st = FileUpload1.PostedFile.InputStream; string name = Path.GetFileName(FileUpload1.FileName); string myBucketName = "*******"; //your s3 bucket name goes here string s3DirectoryName = ""; string s3FileName = name; bool uploaded; UploadFiles myUploader = new UploadFiles(); uploaded = myUploader.sendMyFileToS3(st, myBucketName, s3DirectoryName, s3FileName); }I got the error st.ReadTimeout' threw an exception of type 'System.InvalidOperationException on the below line
Stream st = FileUpload1.PostedFile.InputStream;
Please suggest

File upload in Web Forms is well documented with wonderful examples that work perfectly.
https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.webcontrols.fileupload?view=netframework-4.8
Can you explain why you are accessing the InputStream and the problem you are trying to solve at a high level so we are not guessing? Seems like you are trying to forward the stream? If that's the case then you'll need to read the stream into a buffer and forward the buffer.

Sir, because my class takes stream as a parameter.
public bool sendMyFileToS3(System.IO.Stream localFilePath, string bucketName, string subDirectoryInBucket, string fileNameInS3) { IAmazonS3 client = new AmazonS3Client(RegionEndpoint.APSouth1); TransferUtility utility = new TransferUtility(client); TransferUtilityUploadRequest request = new TransferUtilityUploadRequest(); if (subDirectoryInBucket == "" || subDirectoryInBucket == null) { request.BucketName = bucketName; //no subdirectory just bucket name } else { // subdirectory and bucket name request.BucketName = bucketName + @"/" + subDirectoryInBucket; } request.Key = fileNameInS3; //file name up in S3 request.InputStream = localFilePath; utility.Upload(request); //commensing the transfer return true; //indicate that the file was sent }All-Star

That's a a design detail not the high-level problem you are trying to solve.
I'm pretty sure in ASP.NET you need to read the file stream into a buffer first. Then pass the buffer to the sendMyfilesToS3() method.
https://docs.microsoft.com/en-us/dotnet/api/system.web.httppostedfile.inputstream?view=netframework-4.8
Have you verified the sendMyfilesToS3() works? I would expect a content-length so the receiver know how many bytes to expect.

Now it is working fine, without any issue.
private string bucketName = "********"; private string keyName = "New Microsoft Word Document.docx"; private string filePath = "D:\\MyData\\*****\\New Microsoft Word Document.docx"; public void UploadFile(string bucketName,string keyName, string filePath ) { try { var client = new AmazonS3Client(RegionEndpoint.APSouth1); PutObjectRequest putRequest = new PutObjectRequest { BucketName = bucketName, Key = keyName, FilePath = filePath, ContentType = "text/plain" }; PutObjectResponse response = client.PutObject(putRequest); } catch (AmazonS3Exception amazonS3Exception) { if (amazonS3Exception.ErrorCode != null &&(amazonS3Exception.ErrorCode.Equals("InvalidAccessKeyId") ||amazonS3Exception.ErrorCode.Equals("InvalidSecurity"))) { WebMsgBox.Show("Check the provided AWS Credentials."); } else { WebMsgBox.Show("Error occurred: " + amazonS3Exception.Message); } }Only the issue is that I am saving first it on my root's local folder that uploading to bucket. like below
FileUpload1.SaveAs(Server.MapPath("MyFolders/" + filename));Because without this I am not getting the file path. I was willing to upload it directly without saving on my root's folder

Hi demoninside,
According to your requirements and the code your provided, it is not permissible that put the inputstream directly into Amazon s3 client.
I suggest you could change your InputStream into byte[], then proceed to your next steps.
Here is the mehod about how to make inputStream into byte[] :
public static byte[] ReadFully(Stream input) { byte[] buffer = new byte[input.Length]; //byte[] buffer = new byte[16 * 1024]; using (MemoryStream ms = new MemoryStream()) { int read; while ((read = input.Read(buffer, 0, buffer.Length)) > 0) { ms.Write(buffer, 0, read); } return ms.ToArray(); } }Best Regards,
YongQing.
